So.. My ryu.conf file looks like default and I'm running this BGP code as a Ryu application.
I'm using the app_manager.RyuApp class to make it a Ryu application and running along with a simple switch on ryu-manager. Greetings. ________________________________ De: Victor Orlikowski <[email protected]> Enviado: sexta-feira, 19 de agosto de 2016 12:42 Para: Paulo Sérgio Cc: [email protected] Assunto: Re: [Ryu-devel] BGPSpeaker - shutdown error.

What does your ryu.conf look like? This *looks* like the OpenFlow controller portion of the code is being instantiated that way. Otherwise, the BGP protocol code should not be loading the OpenFlow portions at all, that I can tell. Best, Victor -- Victor J. Orlikowski <> vjo@[cs.]duke.edu
